Answer 1

r = 5.6

Explanation:

3r(6/2) = 7(2r-4)

9r = 14r-28

9r-14r = -28

-5r = -28

-5r/-5 = -28/-5

r = 5.6

Answer 2

Starting with the left side of the equation:

3r(6/2) = 9r

Now, we can simplify the right side of the equation:

7(2r - 4) = 14r - 28

So now we have the equation:

9r = 14r - 28

Subtracting 9r from both sides, we get:

0 = 5r - 28

Adding 28 to both sides, we get:

5r = 28

Finally, dividing both sides by 5, we get:

r = 5.6

Therefore, the solution to the equation 3r(6/2) = 7(2r - 4) is r = 5.6.
